AI-Powered supplier vetting

SummaryThe supplier is presented as a professional technical HVAC/R supplier with production lines, moulds, patents, and a complete HVAC/R product range. It reports ISO 9000 and ISO 9001 management-system certifications and states that most products hold CE, RoHS, and UL approvals. Customization is available from samples and designs, including full, minor, and flexible customization. However, the supplier does not provide 3D software design, ODM, SDK, or well-known-brand OEM services, and launched no new products in the past year. It has no overseas warehouse, showroom, agent or branch, and has not participated in offline trade shows. Service quality assurance is stated, but complaint handling and corrective-action arrangements are described only as “Others.” Financial records are referenced for 2022–2024, but no financial performance details are provided. No specific customer cases are identified.

Supplier typeThe supplier is explicitly identified as a professional technical supplier and describes a complete HVAC/R range with production lines, moulds, patents, and one-stop solutions. Its stated business scope also covers hardware, building materials, mechanical equipment, refrigeration and air-conditioning equipment, and related technical services.

CertificationsThe supplier reports ISO 9000 and ISO 9001 management-system certifications. It also states that most products are approved by CE, RoHS, and UL, although the evidence does not indicate that every product holds these approvals.

R&D capabilityThe supplier has R&D capability, patents, and states that it continues to innovate and improve technology. Conversely, it launched no new products in the past year and does not provide ODM, SDK, or 3D software design services, indicating some limitations in documented innovation-service breadth.

Production capacityThe supplier states that it owns a series of production lines and moulds and provides a complete HVAC/R product range. Its business scope includes sales of refrigeration and air-conditioning equipment and related industrial products, supporting production-related capability, although no capacity or output figures are given.

Customization capabilityThe supplier explicitly offers customization from samples and designs, as well as full, minor, and flexible customization. This supports a broad customization offering, but 3D software design is not available.

Product Q&A

Q:Can the EV series be used as an air inlet?

While optimized for exhaust, the EV can work for supply air in smaller spaces. For better air distribution, our SV (Supply Valve) series is recommended.

Q:How to ensure the selection matches the pipeline?

Match your duct's inner diameter. For a 100mm pipe, choose EV 100. Its slightly smaller 'D' dimension ensures smooth insertion when used with the mounting collar.

Q:Will it rust in humid environments like a bathroom?

No. The heavy-duty powder coating is much thicker and denser than standard paint, providing long-term corrosion resistance in high-humidity areas like bathrooms.

Q:How to quickly restore the original airflow settings after cleaning?

Mark the threaded spindle or measure the disc depth before removal. Simply screw it back to the same position after cleaning to maintain your original airflow settings.

Q:Can it be installed on a gypsum board ceiling?

Yes. Use the provided mounting collar to secure it to the ceiling cutout. The sponge gasket will hide any rough edges and ensure an airtight seal against the drywall.
